Caroni was founded in 1925, when Jean Caroni, a former GTM engineer, decided to create his own company in the north of France. Under his helmsmanship, Caroni became a specialist in pile driving and sheeting and earthmoving works. During the post-war reconstruction period, the company built the Don-Sainghin lock, one of the largest in France at the time. In 1950, it rebuilt the Denain lock. After that, it developed other construction activities, becoming a construction specialist in the process. CBC acquired the company in 1983.
